My Quotation

Hi, anyone heard of a company called “One Power”? I have received a quote for a 6.6kv system, 22 panels using Q-Cell G5 260-280. The inverter is a Sunpower SG5K-D. The quote was $9,222 cash including installation. My fuse box needs an upgrade (pretty old) and they want to charge $900 for that.

That quote for the fuse box sounds about right. We had ours replaced about 2 years ago and it cost $800.

Hi @jarama, I think that might be a Sungrow inverter, not SunPower. Easily confused, but quite different companies.

Seems in the expensive side, I would get more quotes. Switchboard upgrade cost is about right, but is it included in the quote, or additional?

Cheers
